To all whom it may concern:

Be it known that 1, SYDNEY I. PRESCOTT, a citizen of the United States, residing at New York, county of Kings, and State of New York, have invented certain new and useful 1m rovements in Paper-Strip Controlling an Printing Mechanism for Cigarette-Ma chines, fully described and re resented in the i following specification, and t e accompanying drawings, forming a part of the same.

This invention relates to certain improvements in tube forming mechanisms of the l kind employed in forming a thin continuous aper strip into a tube, such mechanisms eing use in connection with cigarette Inachines. In such mechanisms, the aper strip is continuously drawn by the tube 'orming means from a suitable source of supply, such, for instance, as a reel. The paper emloyed, however, is very thin and it is difficult to maintain the exact amount of tension on it which is necessary to enable the tube forming means to perform their function with that accuracy required for the formation of perfect tubes.

The present invention has for its object to roduce a mechanism for use in connection with devices for making a continuous tube, said mechanism operating to relieve the strains on the continuous paper strip and at the same time maintain a proper tension on the strip, so that the tube forming devices may operate with accuracy. A further object of he invention is to produce amechanism for use in connection with tube forming devices of the character referred to which shall relieve the strain and the continuous paper strip and which may, at the same time, be emp oyed for effecting other functions such as printing and bronzing.

Referring to the drawings Figure 1 represents a plan view of a forming mechanism embodying the invention. Fig. 2 is a side elevation of the construction illustrated in Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is a section on the line 4- 1 of Fig. 2. Fig. 5 is an elevation of the gearing which may be employed. Fig. 6 is a section on the line 6 of Fig. 1'.

Continuous tube forming mechanisms of the character to which this invention is par tieularly applicable are used for the purpose of making tubes for cigarette machines, and

it is customary to a such as trade mar paper strip prior to a tube. mechanism invention will, in of such a character for the purpose of ply disti {S or trade the time it is The strain re which forms the subj the best cons that it may JERSEY.

The roll 23 is positively d with the the construction illustrated, the shaft usual bearer flanges 29 to regulate the force of the im ression on t e paper strip. In order to acilitate threading the paper heprinting rolls, either the printing tween the or impression roll may be made movable. In 12 (see Figs. 1 and 6) purpose of threading the paper strip through t e Inec anism, to bring the printing roll back into exact adjustment it formerly occupie strip. In the best constructions, furthermore, this traveling surface or surfaces ma be utilized for applying bronze to the freshly In the particular construc 44, 45, these being mounted on a positively driven shaft 46, 47, 48. heel 37 is a bronze applying wheel and is provided with an applying surface or pad ta 'ng bronze from a pickup Wheel 50 mounted on a positively driven shaft 51, this wheel and the wheels 37, 38 and 39 running in a bronze box 52.

The construction is such that the printing Wheel of the strip and the bronzing wheels mm at a speed somewhat in excess of the speed of the strip, so that they exercise a kind of drawing or combing action on the strip, thus relieving the strain set up by the drawing action of the tube orming devices. The'speed should, however, be so calculated as to maintain that tension on the strip which is necessary for e accurate operation of the forming devices.

In the particular construction illustrated, the power for driving the various shafts referred to is derived from a driving shaft 53 which may be one of the way-shafts of the machine and driven in any suitable manner. gear 54 which meshes with a similar gear 55 on a stud 56. This spiral the frame of the rel This shaft is provided with a spiral fountains Wlll be ing or bronzing takes gear carries a] gear which is located. directlybehind it, this gear meshing with a gear 57 on the shaft 42 before referred. to which is the shaft on which the bronzing wheel 39 is mounted. be remarked that the wheel 39 as the wheel 38 are brushing wheels which dust off the excess of bronze applied by the wheel 37 and are provided with the usual pile surfaces, as indicated in the drawings.

The gear 57 is in mesh with a gear 58 on the shaft 48 and also with an idler 59 mounted on the stud 60. T is idler is in mesh with a gear 61 on the shaft 41-the shaft of the wheel 38. he gear 61 is in mesh with a gear 62 on the shaft 47' of the wheel 44. The gear 61 is also in mesh with an this gear being in the shaft 46. Th with mesh with a gear 66 on e gear 65 is also 1n mesh movement. idler 72 mounted on a stud 73, this idler being in mesh with a which is the shaft of This idler 73 is also 1n leaving the bronzing wheel, the paper strip may run over a guide wheel 80 mounted on a shaft 81, this shaft being provided with a gear 82 which is in mesh with the gear 58 before referred to.

It will be observed that the gearing is of such a character that all the shafts run at the same surface speed. It will, however,

e further observed that the diameter of the 39 and their companion greater than the diameter of the printing wheel, which wheel struction illustrated, at the speed given the strip by the tube forming devices. The traveling or surface speed of these wheels 37, 38, 39, 43, 44, 45 is therefore in excess of the speed of the strip, and, therefore, exercises a strain relieving function, as has been before indicated.

f it be wheels before referred to simply emptied, so that no printlace. anges ,and variations may be made in the construction by which the invention is carried into eflect. The invention is not, therefore, to be limited to the specific construction hereinbefore described and illustrated.

What is claimed is 1. The combination with mechanism for forming 'a thin paper strip into a tube, of a source of supply from which the strip is continuously drawn, a traveling surface located and operating on the strip between the source of strip supply and the forming means, and means for driving the surface at a speed in excess of the speed of the strip.

2. The combination with mechanism for forming a thin paper strip into a tube, of a source of supply from which the strip is continuously drawn by the forming mechanism, a plurality of wheels located between the source of supply and the forming means, and means for driving some of the wheels at a speed in excess of the speed of the strip.

3. The combination with mechanism for forming a thin paper strip into a tube, of a source of supply from which the strip is continuously drawn by the forming mechanism, a plurality of pairs of wheels between which the strip passes, said wheels being located between the source of supplyand the forming mechanism, and means for driving some of the pairs of wheels at a speed in excess of the speed of the strip.

4. The combination with mechanism for forming a thin paper strip into a tube, of a source of supply from which the strip is continuously drawn by the forming mechanism, a pair of printing wheels, and a revolving strain relieving mechanism between the printing wheels and the forming mechanism, with which relieving mechanism the strip is in contact, said relieving mechanism moving at a greater speed than the speed of the strip.

5. The combination with means for forming a thin paper strip into a tube, of a source of supply from which the strip is continuously drawn by the forming means, a pair of printing wheels in the path of the strip, bronze applying means in the path of the strip, and means for driving the bronze applying means at a greater speed than, the speed of the strip whereby said bronze applying means also operates to relieve the strain on the strip.

6. The combination with means for forming a thin paper strip into a tube, of a source 01 supply from which the strip is continuously drawn by the forming means, a pair of printing wheels in the path of the strip, a set of bronzing wheels in the path of the strip, and means for driving the bronzing wheels at a greater speed than the speed of the strip whereby said bronzing wheels also operate to relieve strain on the strip.

7. The combination with means for forming a thin paper strip into a tube, said means including a pair of crimping wheels, of a source of supply from which the strip is continuously drawn by the crin'iping.wheels, a pair of printing wheels in the path of the strip, a set of bronzing wheels in th" path of the strip, and means for driving the bronzing wheels at a greater speed than the speed of the strip, whereby said bronzing wheels also operate to relieve strain on the strip.
